TROLLEY-WIRE HANGER.

SIPECIFIGATION forming .part of Letters Patent No. &338,391, dated April 30, 1895.

Ap lication filed March 5, 1895. Serial No. 540575. (No model.)

To all whom it may concern:

Be it known that I, WALTER R. Sco'rr, a citizen of the United States, residing at Buffalo,

in the county of Erie and State of New York,

have invented a new and useful Improvement in Trolley-VVire Hangers, of which the following is a specification.

This invention relates to that class of trolley hangers or supports which are provided with a longitudinal seat or groove in which the trolley wire is retained by a clamping device bearing against the wire.

My iuvention has for its object to provide the hanger with a simple clamping device which firmly holds the wire in its seat and which is reliably locked in position.

In the accompanying drawings, Figure 1 is a side elevation of my improved hanger attached to a trolley-wire. Fig. 2 is a horizontal section thereof in line 2 2, Fig. 1. Fig. 3 is an end View showing the trolley-wire in cross-secton.

Like letters of reference refer to like parts in the several figures.

A is an upright plate forming the body of the hanger and having at its upper end a socket or enlargment A', or other suitable means for attaching it to the usual span or cross wire, or to the arm of a trolley pole. The bodyA is provided at its enlarged lower end with a seat b which receives the trolley wire O and which consists preferably of a longitudinal lip or flange, of curved cross section, extending laterally from the lower portion of the hanger body.

D D represent a pair of clamping cams or eccentrics arranged on the body A, above the seat or lip b, and adapted to bear with their lower faces against the upper side of the trolley wire, so as to hold the latter tightly in its seat. These cams or eccentrics are mounted upon horizontal studs or pivots e projecting from the adjacent side of the body and having their outer ends headed or upset to retain the cams thereon. These cams are preferably so pivoted that the greatest radius of each is on the inner side of its pivot, whereby both cams clamp the trolley wire when turned outward, or in the direction of the arrows shown in Fig. 1, while releasing their grip on the wire when turned in the opposite direction. By this arrangement, in case the wire is subthereof seatedin the lip b will be retained in place by the cam on the left hand side of the hanger, thus preventing both sections of a parted wire from beooming detached from the hanger. The cams are caused to grip the trolley wire more tightly the greater the longitudinal strain upon the wire.

F is a lock whereby the cams or eocentrics are prevented from turniug out of their clamped position and releasing the trolley wire. This lo'ck preferably consists of a V- shaped spring or spring plate arranged hori zontally between the two cams or eccentrics and bearing with its ends against the opposing portions of the same. The end portions of the locking spring are bent parallel with the side of the hanger body and are seated iu Vertical recesses or rabbets d forned in the opposing edges of the cams, as shown in Fig. 2, whereby the spring is confined against outward displacement between the recessed portions of the cams and the adjacent side of the hanger body. The looking spring, while preventing the cams fromturniug toward the cams are turned inward suficiently to` permit the wire to be placed in its seat. After inserting the wire, the cams are turned outward to clamp the wire, and the looking spring is theu inserted in the recesses of the cams by introducingit from the upper ends of the latter. When it is desired to release the wire for making repairs, or for any other purpese; the spring is withdrawn from the recesses of the cams, whereupon the latter can be turned for releasing the wire. The hanger is preferably constructed of brass or other malleable metal and its lip b and the pivots of the clamping cams are formed integrally therewith. A

I claim as my invention- 1. In a t'olley wire hanger, the combination with the body of the hanger provided at its lower end with a laterally extending lip or fiange extending from end to end of the body and forming a seat for the trolley wire, of a clamping earn or eecentre pivoted to the body above said lip or fiange and adapted to bear against the trolley wire, substantially as set forth.

2. The combination with the body of the hanger provided with a. seat for the trolley wre, of a pair of cams or eceentrics pivoted to the body abovesaid seat, and a lock engaging with said cans or eecentrics, substantially as set forth.

3. The eombination with the body of the hanger provided with a seat for the trolley wire, of a par'of earns or eeeentres pivoted to the body above said seat, and a looking device interposed between said eams and bearing against the opposing edges the'eof, substantially a's set forth.

i. The oombination with the body of the hanger provided With a seat for the trolley Wire, of a pair of eams or eeeentries pivoted to the body above said seat and provided in their opposing edges with upright reoesses, and a V-shaped looking spring arranged with its end portions in the recesses of said czuns or eeeentries, substantially as set forth.

W'itness my hand this 23d day of February, 1895. r

WALTER R. SCOTT.
